Experimental treatments with Orbicella species recruits from two cohorts born in 2019 and 2020 (indicated by subscripts and size of the polyp icons). (A) Experiment 1: Staged pairs of Orbicella faveolata (blue) and Orbicella annularis (orange) recruits from two cohorts examined for induced chimera formation. The 2019 cohort was 6 mos of age and the 2020 cohort was 18 mos of age at the start of this experiment. The first four treatments (T1-T4) matched the same species and cohorts (intraspecific pairs). The remaining three treatments (T5-T7) combined pairs of recruits from different species or cohorts. (B) Experiment 2: All successfully fused chimeras of each Orbicella species from Expt 1 were outplanted on the reef alongside singleton colonies divided into two size class treatments: Large (L; > 10 mm) and Small (S; < 10 mm). Members of singleton treatments were pooled from colonies of both age cohorts (indicated by subscripts). The shaded box indicates chimeras which were excluded from statistical analysis in order to standardize colony size between chimeras and large singletons. n: number of replicates per treatment; Ø indicates mean diameter (± 1 standard deviation) per treatment.
